IMPROVEMENT IN RESERVOIR COGKING-STOVES.

Specification forming part of Letters Patent No. 164,735, dated June 22,1875; application filed May 2o, 1815.

To all whom it may concern Be it known that l, RICHARD M. HER- MANCE, of Half Moon, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Cooking-Stoves, of which the following is a specitication:

The objects of my present invention are, first, to provide means for heating the reservoir in an effective aud economical manner by hot air, in contradistinction to smoke or the products of combustion 5 and, second, to utilize the walls of the ducts or flues for this hot air as ribs or strengthening portions for the top plate of the stove and its adjuncts; to accomplish all of which the invention consists, rst, in the combination of a hot-air flue passing through the center of the top sheetflue of the stove, a reservoir located in rear of the ordinary pipe-collar, and a reservoircasing provided with outlets for the heated air, which are located beneath the plane of the top plate of the stove; second, in the combination of a hot-air lue passing through the center of the top sheet-due of the stove,

a reservoir-casing situatedin rear of the rear lines, and the descending flues, into which the air escapes after imparting its, heat to the reservoir; third, in the .combination of a hotair flue passing through the center of the top sheet-line ot' the stove, a ,reservoir-casing located in rear o f the rear dues and provided with division-strips, and the descending flue,

into which the heated air escapes; fourth, in the combination of a hot-air flue passing through the center of the top sheet-flue of the stove, a reservoir-casing located in rear of the rear flues and provided with division strips, and a port or ports leading from said casing, and permitting the air to escape at a point below the top plate of the stove; fifth, in the combination of the bridge or partD and its subjacent hot-air due; sixth, in the combination of the hot-air llue passing through the center of the top sheet-due of the stove, carrying heated air to the reservoir-casing, and the protecting-chamber located between the ovenO and fire-box G; seventh, in the combination of the reservoir-ca sing and bifurcated hot-air flue leading from the front of the stove Vview of an ordinary three-lined cook-stove,

having the parts with which my improvements are connected assembled for use. Fig. 2 is a longitudinal section through the ascending flue. Fig. 3 is a rear view, showingin perspective the arrangement of different parts, with the top plate and reservoir removed. Fig. 4 is a perspective view oi' the top plate inverted, showing the hot-air flue and its connections.

A is the reservoir, the contents of which are to be heated. B is the top plate of the stove, beneath which is located Vthe hot-air duct or liuc c, which flue passes through the center of the ordinary top sheet-flac of the stove. U is the reservoir-casing,- adapted to contain the reservoir, and provided with channels for the heated air. Connecting with the 4ilue c, which leads to the front of the stove,

and takes air from beneath the molding surrounding the top plate, is the Iiue or chamber `I cause the air-duct to separate into two branches, c c, Fig. 4, on each side of said damper. These branches connect with the flues f f, which lead to the reservoir-casing, having their outlets at g g, through the back plate of the stove. .The air-flue c, whethercast with the top plate or made separate and attached thereto, forms a good support therefor, preventing warping and breaking in a very effective manner, and this function of the flue is specially advantageous in respect to the bridge or part D, beneath which it also extends. Inordertothoroughlyheatthereservoir and its contents, I form a depression, E, in the casing, and allow the air to circulate beneath a portion of the bottom of the reservoir before passing out of the casing, 'and for cess.

' at which point its heating properties are most advantageously expended, I place a horizontal strip, as m,in the vertical air-space. When the fire is built and the reservoir in place, it will be seen that the heated air enters the :reservoir-casing at g, is caused to pass around the strips g, and thence out at p, a small opening into the descending lues. The plate m is provided with an aperture, a', and the back plate of the stove with a similar opening or port, y, through which the air may be allowed to escape into the ascending tlues, under the reservoir, or through the ascending iue into the pipe. In either case the heated air finds its exit at a point below the plane of the top plate of the stove-an im portant feature ofmy invention, and one which enables me to apply my improvements to many reservoirstoves now in use, with but slight and inexpensive alteration or addition, rendering them more cfiicient and less objectionable than at present.

Dampers may be applied at the inlet and outlet ports of the casing. as well as at the inlets for the hot air at the front of the stove, anda connection between the oven and the hotair line may be employed for the purpose of ventilatin g the oven.

From the foregoing it will be seen that "ai-r may be introduced through either or both of the air-passages about the fire-pot, and also that the construction herein embodied is applicable to all classes of cooking-stoves and ranges. When the invention is applied to ranges, the heated air is taken from the front' of the fire box, and the reservoir is secured at one end of the range, or opposite to the fireboX, the pipe-hole being on one side. It will also be evident that two or more of the hotair flues may be employed for taking the hotair to the reservoir.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

l. The combination, substantially as before set forth, of an air-flue passing through the center of the top sheet-flue, a reservoir located in rear of the ordinary pipe-collar, and a reservoir casing provided with outlets for the heated air, which are located beneath the plane'of the top plate of the stove.

2. The combination, substantially as before set forth, of an air-flue passing through the center of the top sheet-line, a reservoir-casing situated in rear of the rear ilues, and the descending flue, into which the air escapes after imparting its heat to the reservoir.

3. The combination, substantially as before set forth, of an air-flue passing through the center of the top sheet-line, a reservoir-casing located in rear of the rear 4flues and provided with division-strips, and the descending lues, into which the heated air escapes.

4. The combination, substantially as before set forth, of an air-flue passing through the center of the top sheet-flue, a reservoir-casin g located in the rear of the rear fines and provided With division-strips, and a port or ports leading from said casing, and permitting the air to escape at a point below the top plate of the stove.

5. The combination, substantially as before set forth, of the bridge or part D and its subjacent hot-air iue.

6. The combination, substantially as before set forth, of the air-lue passing through the center of the top sheet-flue, carrying heated air t'o 'the reservoir-casing, and the protectingchamber located between the oven O and firelboX G.

7. The combination, substantially as before set forth, of the reservoir-casing and the bifurcated air-flue leading from the front of the stove to said casing, and passing the draftdamper, as described.

8. The combination, substantially as before set forth, of the ilues 0 c c, casing B, and iue f, formed by the strips q q.

In testimony that I claim the foregoing I have hereunto set my hand.

RICHARD M. HERMANOE.
